Abstract
The invention relates to a method for high-temperature galvanization of ferrous material parts (10). The method comprises the production of zinc melt (12). The method further comprises saturating the iron concentration of the zinc melt (12) so that it is iron-saturated. In addition, the method comprises producing an undersaturation of the iron concentration of the zinc melt (12) so that it is iron-undersaturated. The method further comprises dipping the ferrous material parts (10) in iron-undersaturated zinc melt (12), whereby a galvanization layer (14) is formed on the ferrous material parts (10).
Claims20
A method for high-temperature batch galvanization of ferrous material parts, comprising:
- generating a zinc melt, wherein the zinc melt has a temperature of at least 500° C.;
- saturating an iron concentration of the zinc melt so that it is iron-saturated;
- increasing the temperature of the zinc melt to a series of consecutive target temperatures;
- and
- at each target temperature in the series of consecutive target temperatures:
- (i) establishing an undersaturation of the iron concentration of the zinc melt so that it is iron-undersaturated;
- and
- (ii) dipping a respective batch of ferrous material parts into the iron-undersaturated zinc melt, wherein a respective galvanization layer is formed on the respective batch of ferrous material parts.
